IPv6 Deployment

The core of the LEARN Network supports IPv6, with the exception of about 5 sites sites connected through the IP-VPN network of Sri Lanka Telecom.

We have obtained a provider-independent IPv6 address space 2401:DD00::/32 from APNIC, and are peering with Sri Lanka Telecom (SLT) on IPv6 since Oct 2008. We are peering with the TEIN3 Network since April 2010. The peering with the TEIN3 network includes IPv6 multicast routing.

The core servers of the LEARN network and some campus networks are already running IPv6 (see the table below).

Access routers at all the sites listed in the table below are IPv6 ready. Therefore at least the hosts/servers on the IP network directly connected to the LEARN access router can run IPv6.

The status of IPv6 deployment in the core of the LEARN network and member sites is shown below.
